Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária; Na literatura é demostrado algum desconhecimento relativamente à inclusão e impactação do terceiro molar, não sendo ainda possível esclarecer a sua etiologia. Vários estudos têm sido feitos relativos à prevalência destas retenções na cavidade oral mas ainda não foi possível chegar-se a um consenso. O objetivo principal deste estudo foi avaliar a prevalência de terceiros molares inclusos e impactados numa população da Universidade Fernando Pessoa e caracterizar a posição das peças dentárias verificando a relação segundo algumas variáveis. Foi realizada uma revisão bibliográfica narrativa do tema com as palavras- chave: “third molar”; “impaction”; “inclusion”; “third molar pathologies”; erupted third molar”; retained third molar”; “unerupted tooth”; “prevalence of third molars” ; “third molar AND impacted ”; “third molar AND inclusion”; “wisdom tooth”. Os motores de busca utilizados foram a PubMed, Scielo, Science Direct, e B-On. Posteriormente foi realizada uma investigação científica com uma amostra de 250 ortopantomografias dos processos clínicos das Clínicas Pedagógicas da Universidade Fernando Pessoa dos pacientes com idades iguais ou superiores a 18 anos no período de 2009 a 2013. No estudo realizado verificou-se que a prevalência de terceiros molares inclusos ou impactados seria de 21% com intervalo de confiança a 95% e poder estatístico 20%. A proporção apresentada dos pacientes que apresentavam pelo menos um terceiro molar incluso ou impactado situou-se entre 19...

Diante da importância da avaliação radiográfica, foram estudadas as classificações de várias características dos terceiros molares, por meio de panorâmicas, sendo investigado suas possíveis correlações com o estado de impactação óssea. Informações referentes aos dentes foram coletadas em relação ao estado de impactação ou inclusão óssea (de acordo com a formação radicular), espaço disponível, posição do longo eixo, profundidade óssea, relações com o dente adjacente, com o seio maxilar e com o nervo alveolar inferior. Além disso, foram considerados as ausências de dentes no hemiarco, a presença de supranumerários, de outros dentes inclusos/impactados, o gênero e a idade do paciente. Ao total, foram analisadas 802 panorâmicas com 2687 terceiros molares, sendo o estado de impactação pesquisado em 2119 desses, nos quais foi possível identificar correlações do espaço inadequado e de algumas posições com a etiologia das impactações, principalmente nos dentes inferiores. As análises dos resultados revelaram que não houve diferenças estatisticamente significantes das características do terceiros molares entre os gêneros e que a freqüência de impactação óssea diminuiu com o avanço da idade. Foi também observada boa concordância entre os dentes do mesmo arco do paciente...

The frequency of simultaneously impacted second and third molars in teenagers is increasing and becoming a common occurrence in adolescent oral surgery practice. The traditional treatment is the removal of the third molar by conventional access but repositioning of the surgical flap to the distal face of the first molar can predispose to complications such as pericoronitis and delayed healing of the attached gingiva. We present a case in which we use the germectomy approach to remove the impacted third molar for the eruption of the second molar through a vestibular incision. This incision offers excellent bone exposure and exit route for the third molar without disturbing the gingiva attached architecture on the distal face of the first molar providing good healing environment.

"Objective: To investigate whether there is an association between dental development anomalies (DDAs) and the different manifestations of Class II Division 2 (CII/2) malocclusion incisor retroclination. This information may clarify whether the different CII/2 phenotypes, with regard to maxillary incisor retroclination, are a single clinical entity or etiologically different entities. Design: Retrospective comparative study. Setting: Private orthodontic practice in the regions of Lisbon and Porto, Portugal Subjects and Methods: The sample comprised 115 CII/2 malocclusions distributed into 2 groups on the basis of incisor retroclination: Group I composed of 48 CII/2 with retroclination exclusively of both maxillary central incisors; Group II composed of 67 CII/2 with retroclination of all four maxillary incisors. Using the initial orthodontic records, it was determined for each patient the presence of the following DDAs: tooth impaction, tooth agenesis, maxillary lateral incisor microdontia, tooth transpositions and supernumerary teeth. Results: 55.0% of patients were diagnosed with at least one of the DDAs studied. In the total sample the prevalence rates were determined as follows: 20.0% of palatal maxillary canine impaction, 27.4% of third molar agenesis...

INTRODUCTION: Even though the upper canine is the tooth that presents most eruption anomalies, after the third molars, canine retention prevalence in the population is quite low. Local, physiologic and pathologic factors can provide difficulties for the tooth eruptive process. The correct diagnosis in trying to prevent upper canine retention with ectopic eruption is fundamental to choose the ideal treatment, which can be performed by various methods. OBJECTIVE: The present paper has the purpose of approaching aspects related to impacted upper permanent canines by a literature review, including localization and treatment conducts.

INTRODUCTION: The early orthodontic treatment allows correction of skeletal discrepancies by growth control, and the elimination of deleterious habits, which are risk factors for the development of malocclusions, favoring for the correction of tooth positioning later in a second treatment stage. During development of teeth and occlusion, the mandibular second molars commonly erupt in the oral cavity after all other teeth of the anterior region. In their eruptive process there may be a condition known as tooth impaction, which precludes its complete eruption and requires proper uprighting treatment. The temporary anchorage devices allow disimpaction and movement of these teeth directly to their final position, without the need of patient compliance or reaction movements in other parts of the arch. OBJECTIVE: This paper aims at describing a case report of the treatment of a patient with Angle Class II malocclusion, performed in two phases, in which mini-implants were used for uprighting the impacted mandibular second molars.

INTRODUCTION: Dental transposition and impaction are disorders related to ectopic eruption or failure in tooth eruption, which can affect child physical, mental and social development and may be difficult to be clinically solved. METHODS: We describe a case of transposition between the upper left canine and lateral incisor associated with impaction of the central incisor on the same side, in a 12-year-old patient. Conservative treatment involving surgical-orthodontic correction of transposed teeth and traction of the central incisor was conducted. CONCLUSION: The option of correcting transposition and orthodontic traction by means of the segmented arch technique with devices such as cantilever and TMA rectangular wire loops, although a complex alternative, was proved to be esthetically and functionally effective.

INTRODUCTION: Although lip bumpers (LBs) provide significant clinical gain of mandibular arch perimeter in mixed-dentition patients, orthodontists are reluctant to use them due to the possibility of permanent second molar eruptive disturbances. OBJECTIVE: The present study was conducted to assess second molar impaction associated with the use of LBs, and to investigate how they can be solved. MATERIAL AND METHODS: Lateral and panoramic radiographs of 67 patients (34 females and 33 males) were assessed prior (T1) and post-LB treatment (T2). LB therapy lasted for approximately 1.8 ± 0.9 years. Concomitant rapid palatal expansion (RPE) was performed in the maxilla at LB treatment onset. Impaction of mandibular second molars was assessed by means of panoramic radiographs in relation to the position of first mandibular molars. Horizontal and vertical movements of first and second molars were assessed cephalometrically on lateral cephalometric radiographs based on mandibular superimpositions. RESULTS: Eight (11.9%) patients had impacted second molars at the end of LB therapy. Two patients required surgical correction, whereas five required spacers and one patient was self-corrected. Mandibular first molar tip and apex migrated forward 1.3 mm and 2.3 mm...

In the present report, a case of 19 year-old monozygotic twin brothers with similar tooth agenesis and impacted primary teeth is presented. Both twins (HDH, DHH) had agenesis of ten and eleven teeth (respectively), third molars excluded, consistent with oligodontia and both had four impacted primary teeth and the permanent successors of all these primary teeth were congenitally missing. The occurrence of similarly located tooth agenesis and primary impacted teeth in monozygotic twins may suggest the influence of genetic factors in their etiology. In addition, primary tooth impaction may be related to congenitally missing tooth.

Primary tooth impaction is a rare finding during the development of primary dentition. Several factors contribute to the impaction of a deciduous tooth. This report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. This tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the premolar teeth. Treatment consisted of surgical removal of the impacted deciduous tooth and odontoma and placement of a passive lower lingual holding arch. Periodic examination was indicated for follow-up. Early intervention was recommended to manage orofacial disfigurement and to avoid consequent problems.

Tooth impaction is defined as any tooth that fails to erupt into a normal functional position and remains unerupted beyond the time at which it should normally erupt. Reports of impaction and eruption failure in primary teeth are relatively rare compared to permanent teeth. We report 2 rare cases where the second premolar was located on the occlusal side of the impacted mandibular second primary molar. In the first case, the succedaneous permanent tooth erupted after extraction of the primary tooth, fenestration, and traction. In the second case, the succedaneous permanent tooth erupted without fenestration or traction. Although the etiology of the tooth displacement was unknown in both cases, inhibition of the eruptive movement of the primary molar may have been associated with displacement of the succedaneous permanent premolar.

Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the anterior border of the ascending ramus of the mandible. Impacted teeth may remain asymptomatic or may be associated with various pathologies such as caries, pericoronitis, cysts, tumors, and also root resorption of the adjacent tooth. Even though various classifications exist in the literature, none of those address the combined clinical and radiologic assessment of the impacted third molar. Literature search using the advanced features of various databases such as PubMed, Scopus, Embase, Google Scholar, Directory of Open Access Journals and Cochrane electronic databases was carried out. Keywords like impaction, mandibular third molar, impacted mandibular third molar, complications, anatomy, inferior alveolar nerve injury, lingual nerve injury were used to search the databases. A total of 826 articles were screened, and 50 articles were included in the review which was obtained from 1980 to February 2015. In the present paper...

Maxillary second molar impaction in the adjacent ectopic third molar is a rare condition that practitioners might face in the field of pediatric dentistry and orthodontics. The early diagnosis and extraction of the adjacent ectopic third molar have been advocated, and prior research has reported a high rate of spontaneous eruption following third molar removal. However, some challenges in the daily practice are that the early diagnosis of this type of tooth impaction is difficult with conventional radiographic examination, and sometimes the early surgical removal of the maxillary third molar must be postponed because of the risks of damaging the second molar. The objective of this study is to report a case series of five young patients with maxillary second molar impaction and to discuss the difficulty of early diagnosis with the conventional radiographic examination, and unpredictability of self-correction.

Tesis para optar al titulo de Cirujano-Dentista; ABSTRACT Impaction has been defined as the maintenance of the tooth in the thickness of bone tissue, beyond the time the tooth eruption should occur spontaneously. The etiology of canine impaction is multifactorial in origin. Among the possible local causes, lack of space is mentioned. The purpose of this study is to determine the presence of impacted canines related to the development of reduced basis maxilla. We proposed the hypothesis that there is a higher prevalence of maxillary canine impaction in skeletal Class III patients with maxillary development deficit compared to skeletal class I or II patients. The universe observed in this study were 419 patients who were treated by the students of the specialty of Dentomaxillary Orthodontics and Orthopedic of University Andres Bello in the period 2011 to 2014. In this study were included patients that had at least one canine with bad prognosis of eruption, based on Lindauer method. In the teleradiography of 46 patients with canine impactation, the anatomical structures were drawn for the cephalometric analysis of Steiner and Ricketts Most patients Class II (52.2%)...

The lack of eruption of a primary tooth can be considered rare. In primary impaction, the primary tooth not only has never appeared in the oral cavity, but also is always covered by a more or less thick layer of bone. Secondary impaction, which is relatively more common, denotes teeth that at one time erupted into the mouth, but subsequently clinically appear to have receded from this position. The purpose of this paper is to present a case of primary and secondary impaction of four primary molar teeth in a single patient.
